Do I need to set up IPV4 specific routes to >a dual stack machine that does the tunneling for me? Your story has nothing to do with auto tunnel. Automatic tunnel (::10.1.1.1) is only for communication between two IPv4/v6 dual stack hosts. For a IPv6-only host (or IPv4/v6 dual stack host without IPv4 address) to communicate with IPv4 host, you need to have IPv6-to-IPv4 translator (TCP relay server like socks or KAME FAITH, or web proxy) between two.
